The working process of the utility model is further described below:

referring to fig. 8 to 11, in an initial state, the reset spring 4 applies the elastic force of the inner cap 31 and the outer cap 32 away from the mounting bracket 22, the inner cap 31 applies the elastic force of the reset spring 4 to the first end of the rotating member 51 through the cooperation of the connecting member 311 and the first rotating shaft 513 so that the first end of the rotating member 51 faces the inner cap 31, the rotating member 51 changes the direction of the force by the lever principle of the second rotating shaft 514, the elastic force of the reset spring 4 is changed to face the mounting bracket 22 so that the second end of the rotating member 51 abuts against the mounting bracket 22, and the elastic force of the reset spring 4 is counteracted by the blocking action of the mounting bracket 22 so that the inner cap 31, the outer cap 32 and the rotating member 51 are movably fixed to the base 2. Meanwhile, the first limit protrusion 512 is closer to the mounting bracket 22 than the second limit protrusion 3111 and the first rotation shaft 513, and the feel spring 52 is inclined toward the mounting bracket 22 in a direction toward the second end of the rotation member 51, so that the feel spring 52 applies an elastic force to the second end of the rotation member 51 to rotate toward the mounting bracket 22, which is also counteracted by the blocking effect of the mounting bracket 22.

When the micro switch needs to be triggered, the user firstly presses the outer cover 32, the outer cover 32 rotates towards the mounting bracket 22 to drive the inner cover 31 to move towards the mounting bracket 22, the inner cover 31 overcomes the elastic force of the return spring 4 and compresses the return spring 4,

simultaneously, the inner cover 31 drives the rotating member 51 to rotate through the cooperation of the connecting member 311 and the first rotating shaft 513, so that the first end of the rotating member 51 rotates towards the mounting bracket 22, the second end rotates towards the inner cover 31, and the first limiting protrusion 512 located at the second end of the rotating member 51 drives the hand feeling spring 52 to rotate around the second limiting protrusion 3111. Since the second limiting protrusion 3111 is located between the first limiting protrusion 512 and the first rotating shaft 513, the first limiting protrusion 512 rotates around the first rotating shaft 513, so that the distance between the first limiting protrusion 512 and the second limiting protrusion 3111 is gradually reduced, so as to drive the hand spring 52 to compress, and further improve the elastic force thereof.

Referring to fig. 12 to 15, when the first limit protrusion 512 rotates to be in line with the second limit protrusion 3111 and the first rotation shaft 513, the spacing between the first limit protrusion 512 and the second limit protrusion 3111 is closest, and the elastic force of the hand spring 52 is strongest, at which time the elastic force of the hand spring 52 is counteracted by the blocking action of the first rotation shaft 513 and the first rotation groove 3112.

As the rotation member 51 continues to rotate, when the first limit projection 512 rotates closer to the inner cap 31 than the second limit projection 3111 and the first rotation shaft 513, the feel spring 52 is inclined obliquely to the inner cap 31 in a direction toward the second end of the rotation member 51, so that the feel spring 52 applies an elastic force to the second end of the rotation member 51 rotating toward the inner cap 31, while the feel spring 52 stretches to further release the elastic force, so that the elastic force applied to the second end of the rotation member 51 by the feel spring 52 further increases. The elastic force applied to the second end of the rotation member 51 by the hand feeling spring 52 toward the inner cap 31 changes the direction of the force by the lever principle of the second rotation shaft 514, the force applied to the first end of the rotation member 51 toward the mounting bracket 22 transfers the force to the inner cap 31 and the outer cap 32 by the cooperation of the first rotation shaft 513 and the connection member 311, so that the user can suddenly become relaxed to press the hand feeling, thereby providing the hand feeling feedback.

Referring to fig. 16 to 19, when the second end of the rotating member 51 rotates to abut against the inner cap 31, the second end of the rotating member 51 collides with the inner cap 31 by the elastic force of the feel spring 52, thereby generating vibration and sound to enhance feel feedback and provide acoustic feedback. And when the second end of the rotating member 51 rotates to abut against the inner cover 31, the rib 312 on the inner cover 31 presses the pressure spring 61 of the micro switch to trigger the micro switch.
